“…This MOF demonstrated efficient extraction of SAs, largely due to its expansive surface area, leading to low limits of detection (LODs, 0.07–0.47 ng/L) in food samples. Similarly, Li's group [31] used a cyclodextrin MOF (CD‐MOF) as an SPE adsorbent coupled with high‐performance liquid chromatography‐ultraviolet detection (HPLC‐UV) to determine various SAs in meat samples. The CD‐MOF displayed efficient extraction capabilities and a short adsorption equilibrium time for SAs.…”

The development of novel sample preparation media plays a crucial role in pharmaceutical analysis. To facilitate the extraction and enrichment of pharmaceutical molecules in complex samples, various functionalized materials have been developed and prepared as adsorbents. Recently, some functionalized porous organic materials have become adsorbents for pharmaceutical analysis due to their unique properties of adsorption and recognition. These advanced porous organic materials, combined with consequent analytical techniques, have been successfully used for pharmaceutical analysis in complex samples such as environmental and biological samples. This review encapsulates the progress of advanced porous materials for pharmaceutical analysis including pesticides, antibiotics, chiral drugs, and other compounds in the past decade. In addition, we also address the limitations and future trends of these porous organic materials in pharmaceutical analysis.

“…synthesized a methacrylate monolithic column and used sodium deoxycholate and a silver daily mobile phase to achieve the baseline separation of five structurally similar coumarins within 6 min, with recovery rates ranging from 87.5-95.0%, a LOD below 0.15 g ml −1 , and a LOQ below 0.30 g ml −1 . (Pang et al, 2019b) prepared MOF-polymer monolithic columns using modified MOF materials and N-methacrylamide as monomers. They were able to extract and purify triterpenoid ursolic acid from Chinese herbal medicine samples with complex matrices, with a LOD and a LOQ of 0.17 μg ml −1 and 0.57 μg ml −1 , respectively, indicating that they can be applied to the determination and enrichment of ursolic acid in routine laboratory TCM samples.…”

The chromatographic column is the core of a high-performance liquid chromatography (HPLC) system, and must have excellent separation efficiency and selectivity. Therefore, functional modification materials for monolithic columns have been rapidly developed. This study is a systematic review of the recently reported functionalized monolithic columns. In particular, the study reviews the types of functional monomers under different modification conditions, as well as the separation and detection techniques combined with chromatography, and their development prospects. In addition, the applications of functionalized monolithic columns in food analysis, biomedicine, and the analysis of active ingredient of Chinese herbal medicines in recent years are also discussed. Also reviewed are the functionalized monolithic columns for qualitative and quantitative analysis. It provided a reference for further development and application of organic polymer monolithic columns.

“…The sorbent, packed into a pipette tip, has been successfully used for the extraction of phenoxy herbicides from cucumber-water extracts [109]. MOFs have also been coated onto polymeric monolithic columns and adopted for the on-line SPE and determination of ursolic acid from several ethanolic plant extracts [110,111] and of aristolochic acid from methanolic plant extracts [112].…”

Analyses in the plant field have to cover a wide range of topics, starting from metabolomics to the quali-quantitative determination of a single or a class of metabolites, often dealing with very complex matrices. The development of an appropriate sample preparation method is fundamental to obtain complete information, because downstream analyses will detect only the metabolites previously extracted. The choice of the proper extraction phase is therefore of utmost importance and the most critical parameter to be considered. Although most of the studies on plants still mainly adopt traditional extraction techniques, a wide number of new phases with improved features in terms of tunability, selectivity and, most important, sustainability have been developed in the past decades and applied to the study of natural products. This review provides an overview of the new extraction phases developed and adopted for the study of plant endogenous and exogenous metabolites.
